>>> chipped keys are not cheap
What is worrying, Murraymints, is that £150 for a key IS cheap! (At least in comparison to what keys for other makes cost).
I paid £750 for my Saab in October, which only came with one key. As the battery in it seemed to be on the way out, I opened it up to fit a new battery. However the two halves didn't fully click together and, a few days later, when I reached for my keys I realised that I'd only got half a key (and, importantly, not the half which would start the car!). A mad panic ensued and I eventually found the missing half on the ground, not far from my car. (The two halves are now firmly sellotaped together!). That made me check on how much a new key would have cost me, which turned out to be just under FOUR HUNDRED QUID, which was roughly HALF of the cost of the car itself!
I'm taking VERY great care of my keys from now on!!!
